IMPROVED EXTENSION-TABLE ROLLER-SLIDE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may con-cern Be it known that I, JACOB DoURsongof Columbus, in the county of Frai'iklin, and State of Ohio,"have invented certain new and useful Improvements in Extension-Table Roller-Slides, and do hereby declare that the following is a full, clear, and exact. description thereof, reference being had to the accompanying drawings,and to the letters of reference marked there- Oil.

The nature of my invention consists in the construc- `tion of a roller-slide for extension-tables, as will be hereinafter fully set forth.

In order to enable others skilled in the art to 'which my invention appertains, to make and use the same, I will now proceed to describe its construction `and operation, referring to the annexed dra\\'ings,in which- Figure 1 is a perspective view of the entire slide;

Figure 2 is a plan view, showing the metallic rollerslide inserted in the wooden slide;

Figure 3 is an end view and Figure 4, a side view of the metallic roller-slide.

A represents the usual wooden slides for extensiontables, having a groove, a., running longitudinally the entire length of the slide.

At the bottoni of the groove a., on' each side, is another groove, b, as plainly shown in fig. 1, and also in dotted lines in lig 2.

In the end of the slide A is inserted the met-al rollerslide," which consists of a bed-piece or key, B, top piece O, and rollers e e.

The key or hed-piece B maybe of any size and shape desired, and inserted in the end of the wooden slide A, as shown in iig. 1, where it is fastened by pins or screws. It the bed-piece or key B is round, as shown in iig. 2, it is fastened by a screw in the centre, so as to balance;

Upon thekey B are placed the two'rollers e e and' the top piecel O, all fastened together by rivets i t.

The rollers Ae e, when 'the two wooden' slides A A are placed together, run in the groove a, and the top piece O projects on the sides of said rollers so as to fit in the grooves b l), and thus hold the two slides A A together.

At the opposite end of the slide A, and in the groove a., is placed a stop, D, to prevent the slides A A from becoming disconnected. v

Having thus fully described my invention,-

XVhat I claim as new, and desire to secure by Let. ters Patent, is

1. The combination of the key or bedlpieee B, rollers e e, and top piece O, all constructed and arranged substantially as and for the purposes herein set forth.

2. In combination with the roller-slide B O c, the

stop I), substantially as and for the purposes herein I set forth.

In testimony that I claim the foregoing, I have here unto set my hand, this 19th day of November, A. I).
